A dynamic wireline resource management scheme for fast handoff in wireless ATM networks

Abstract

A dynamic pre-allocated connection (DPC) scheme is proposed to support fast handoff and to effectively utilize wireline links. Since the proposed scheme uses pre-allocated switched virtual connections (PSVCs), handoff can be quickly executed in real-time with reduced connection overhead. This dynamic resource management scheme increases utilization of wireline links due to statistical multiplexing effects. For a heterogeneous traffic environment the probabilities of new call blocking, handoff call blocking, and fast handoff failure due to a lack of PSVCs are analysed using a birth-death approximation.
